To all whom t may concern:

Be it known that l, Lno SIMMONS, a citizen of the United States ofAmerica, and a resident of Vashington, District of Columbia, haveinvented certain new and useful lmprovements in and Relating to SprayHeads for Shower Baths, of which the following' is a specification.

This invention relates to certain improvements in spray heads for showerbaths and other purposes; and the objects and nature ofthe inventionwill be readily understood by those skilled in the art in the light ofthe Vfollowing explanation of the accompanying drawings that illustratewhat l now believe to be the preferred mechanical expression orembodiment of my invention from among other forms, constructions andarrangements within the spirit and scope thereof.

An object of the invention is to provide an exceedingly simple andeffective device for producing a water shower for shower bath purposesthat will overcome certain disadvantages incidental Vto the" use of theperforated face plate or so-called rose heads,

now generally employed for spray head shower baths, and that willutilize means to form a water curtain and then break up such curtain toform streams or attain the desired spray all without the use of a closedhollow head having its outlet side closed by a perforated face plate orwall.

With this and other objects inrview my invention consists in certainnovel features in construction and in formations and arrangements offeatures, as more fully and particularly hereinafter explained andspecified.

Referring to the accompanying drawings, forming part hereof:

Fig. l is a vertical section of a shower bath spray device embodying myinvention.

Fig. 2 is a section on line 2 2 of Fig. 1.

- My invention embodies a cavity of preferably substantial depth orlength, closed except at its large open outlet end, and providing anunbroken annular approximately conoidal wall curving inwardly andlongitudinally of the "cavity from an annular orv circular water curtainbreaking-up rim surroui'idingthe open end of the cavity, to thedepressed centerV of the closed end of thecavity constituting theapproximate apex of the wall. The interior surface of this cavity,exclusive of said rim, is preferably smooth and formed to cause th'ewater from ln the particular example illustrated by the accompanyingdrawings, l show an embodiment of my invention formed and arranged tospray the water downwardly and constitute an overhead spray head, thatein-- bodies a depending hollow head or belll of approximate conoidalshape and open at its comparatively large end. l

The lower circular or annular edge ,por-

tion of this hollow head that surrounds the large bottom opening, isformed4 at its an-v nula'r inner surface to provide a toothed orirregular water separating or breaking up annular rim 2, as more fullydescribed hereinafter.

The preferably smooth unbroken annular interior surface 3 of the headcurves and contracts or converges upwardly longitudinally of the head,from the rim 2 to the apex or center t which is alined with thelongitudinal axis and center of the open bottom of the head and locatedat the extreme inner end or top of the interior of the head.

The water, under1 head orv pressure, is introduced from a point withinAthe head in the form of a centrally arranged upwardly directed singlestream or j et directed against the closed center or apexd in the lineof the longitudinal axis of the head. The interior surfaces 3, 4, areintended and designed to cause the jet of water to spread evenly overand cover the surface 3 and descend along said surface in the form of anunbroken annular stream or curtain until the rim 2 is encountered. Thisrim 2 is designed to separate this (what is then a hollow cylindrical)curtain intol an annular series of parallel separate streams that willfall from the lower edge of the head to perform shower bath functions.

The interior surfaces 3, t, are so designed -as to reduce to theminimum, possiblity of the water jet being so sprayed or otherwisebroken up by engagement with the center 4f as to drop vertically fromthe upper end of the head through the openbottom of the head. On thecontrary, the interior surface formation of the head is designed tocause the water to spread approximately uniformly radially from the apexel as a center and closely followY the surface 3 downwardly in a smoothstream completely covering said surface without substantial dripping ordropping therefrom until thel rim 2 is reached.

In the example illustrated, the water is discharged under pressureupwardly centrally against the apex l,'in the forni of a jet, from avertical nozzle centrally arranged within the head andspaced a Vshortdistance from saidapex. rIhis nozzle 5, can becarried by an angle supplypipe 6, lo cated within the head and carried thereby and extendingradially from and secured to the shell or wall thereof.

The pipe 6 can be connected with and supplied from the water supplysystem of the building, through the medium of water supply pipe 7.screwed into a tapped water supply duct 8 extending radiallythrough theshell or wall of the head to supply pipe Vo.

The spray head l can be mounted or supported so as to depend at thedesired distance above the floor, inany suitable manner or by anysuitable means. For instance, I show the head formed with a cent-ralexterior top boss 9, having a tapped socket 10, receiving post 1ldepending from base 12 secured to the ceiling or other overhead support.

.In the particular embodimentJ illustrated as an example. the bottom oroutlet end of the head is entirely open and unobstructed except for theinternal rim 2, although I do not Vwish to so limit all features of myinvention.

.also, in this example, the lower end of the head is internally slightlycontracted in diameter to more or less confine and prevent unduespreadingV of the water shower descending therefrom, and also the waterbreaking up rim embodies an annular series of v similar uniformly spacedradial projections Qa' forming an annular serieswithin the head andradially intersecting the path of the descending annular water curtain,to provide an annular series of intervening uniformly spaced notchesforming vertical Y water passages 2h.

The function of the projections 2a is to sub-divide the annular watercurrent into separate streams that pass down through theV water passages2". Y

This water curtain breaking-up rim 2, can be variously formed to providethe annular series Iof water passages, whether or not provided for'bytheparticular radial internal projections 2a, which in this inst-ance arein the form of radially wedge-shaped. beveled 'or tapered teeththat arevvertically wedgeshapeat their top ends or upwardly beveled to divide thedescending water and concentrate the same in the vertical waterpassages.

It is evident that various changes, modiclosed at the oppositeend toconstitute an elongated approximately conoidal water` cifirtain-formingwall and provided with an internal circular water curtain breaking-uprim around its open end, and means arranged to discharge a water jetwithin the head and centrally against the closed end thereof.

2. A water spraying device comprising'a hollow headclosed at one endandopen at the opposite end for discharge of water in streams for showerbath purposes, and means for discharging a jet of water under pressure,centrally and longitudinally within the head and against the interiorsurface of the closedend thereof, the interior surface of said headbeing formed to cause the water from said jet to spread over'saidsurface and travel toward said discharge end, said head beingformed atsaid discharge end to divide the water into such streams.

3. A hollow head closed Tat one end and formed at the opposite end forwater discharge in an annular series of sprays in combination with anozzle arranged to discharge a water jet longitudinally'.withinfthe headand centrally against the inner surface of the closed end thereof.

4. A hollow head closed at one end and open at its opposite waterdischarge end, the annular internal surface of the head beingapproximately conoidal from the center of said closed end towardthedischarge end, a nozzle arranged to direct a jet of water underpressure centrally against said closed end, means being provided tocause the water to discharge from the head in `spraying streams. i i I5. A hollow head having a closed end and van opposite discharge endprovided with water'curtain breaking-up means, the annular interiorsurface of the head curving and flaring from said'closed end towardsaiddischarge end for outward longitudinal flow of an annular curtain ofwatenand means for discharging a central 'longitudinall Astream of waterwithin theih'ead'and against the inner surface of the closed endthereof.

6. A hollow head closedV atonev end and at the Vopposite end providedwith a surrounding rim of longitudinal separate water dischargepassages, the annular inner surface of the head being ismooth `for Howof water, and a water pipe carried by the head and adapted to beconnected with a building water supply and provided with a waterdischarge arranged to direct a jet of water centrally and longitudinallywithin the head against the interior surface thereof to form an unbrokenannular water curtain moving longitudinally along the inner surface ofthe head to said discharge passages to be thereby broken up anddischarged as spray streams.

7. A hollow head closed at its upper end and open at its lower end andexteriorly formed to be attached to and depend from a support, and awater supply pipe having an upwardly directed discharge arranged todischarge a stream of water longitudinally within the head and centrallyagainst the inner surface of the closed end thereof, the lower end ofsaid head provided with an internal circle of radial inwardly projectingteeth forming intervening longitudinal water passages with the curvedannular inner surface of the head leading thereto.

8. A shower bath water spraying device presenting an approximatelyconoidal cavity having a discharge end with a surround ing water curtainbreaking-up rim, and means to discharge water into the opposite end ofthe cavity to form a water curtain moving towardsaid discharge end.

9. A hollow head having an open discharge end formed to provide a watercurtain breaking-up rim, and means to discharge water into the oppositeend of the head to form a water curtain therein Inoving toward said rim.
